An ordinance amendment passed this week by the city council permits up to three hen chickens on properties that are zoned low-density residential, which is the zoning for more than half of the city's single-family homes. Roosters are prohibited.

The idea was brought to city officials in 2011 by a parent of a 4-H member, but the city council at the time "felt chickens were not appropriate in urban settings," said Tony Whippler, assistant city planner.

Last month, more 4-H parents came to city hall with the idea; the council agreed to reconsider.

Under the new rules, back yards must be fenced or landscaped and include a coop that is at least 10 feet from property lines.

The cost of an annual permit, which is meant to cover the application inspection process, will be set next month.

Burnsville, Eagan and Rosemount are other Dakota County cities that allow chickens.
